Limitations of Electromagnetic Flow Meters at Low Temperatures

Abstract: The limit information of electromagnetic flowmeter at low temperature is provided by excellent flowmeter and flowmeter manufacturers. When the electromagnetic flowmeter transmitter measures low temperature media, it will be bound by two aspects: one is the low temperature resistance function of the material, the output signal of the electromagnetic flowmeter transmitter is small, it is necessary to pay attention to avoid disturbance, the temperature and pressure used Can not be too high, then luck. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of the article on the limitations of electromagnetic flowmeters at low temperatures. When the electromagnetic flowmeter transmitter measures low temperature media, it will be bound by two aspects: one is the low temperature resistance function of the material, the output signal of the electromagnetic flowmeter transmitter is small, it is necessary to pay attention to avoid disturbance, the temperature and pressure used Can not be too high, the temperature used at that time does not exceed 200°. For the medium above minus 20 degrees, the material of electromagnetic flowmeter is usually made of polytetrafluoroethylene. Polytetrafluoroethylene is the most stable plastic in chemical performance, but the thermal expansion and contraction are serious, which is easy to cause electrode leakage. The second is the electrical insulation problem of the electromagnetic flowmeter transmitter. If it is not specially treated, when it is used for the measurement of low temperature medium, the appearance of condensation water droplets or condensation water frost on the outer wall of the measuring tube and the transmitter will easily occur, which will cause The signal is disconnected, the insulation resistance between the circuit and the casing drops, or even a short circuit. The reputation of electromagnetic flowmeters in the industry and customer feedback are satisfactory: high precision, durability, long service life, low failure rate, and good after-sales service. These are the evaluations and affirmations of our customers, which are the driving force for our progress. We strive to develop new technologies, improve product performance, use high-quality materials, and be meticulous about product quality to ensure a 100% pass rate for production testing. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Limitations of Electromagnetic Flow Meters at Low Temperatures'
